Common Heat Pump Problems
At times, heat pumps fail to work as intended. You might find that your unit refuses to turn on, or when it does, it doesn’t heat up as efficiently as it should.
Below are some common problems to look out for. We have also provided ways of fixing up each mishap. Nevertheless, it is always a good idea to call upon a professional to service the unit every once in a while.
What Problems are Likely to Occur?
The Heat Pump Fails to Turn On
This could be caused by one of these failures:
- Problems with the thermostat
Check whether the thermostat’s settings are accurate. If everything checks out, the problem could be a poorly calibrated thermostat. It could also mean that a problem with the electrical connection is preventing efficient communication between the heat pump and the thermostat.
You may need to seek professional services to get the problem resolved.
- Loss of power
A tripped breaker could cause your heat pump to break down. Ensure that all breakers are aligned correctly. If the problem persists, you might need to call a professional to check whether the heat pump has an electrical fault.
- Problems with the starter capacitor
Note the sounds emanating from the unit. If you hear a clicking noise as the pump turns on, the starter capacitor could be broken. This particular accessory transmits the electrical current needed to keep the motors turning. A technician will certainly know how to rectify the problem.
No Heat from the Pump
These are the likely causes:
- There is a blockage in the unit
Air needs to get inside the unit for it to be pumped into your house. If the inlet is blocked by debris, your heat pump will have a hard time doing its job. Luckily, you only need to clear the debris, then clean up the heat pump, and the unit will work as intended.
- A dirty air filter
Air filters block debris and dirt from being blown into your house. However, constant accumulation develops into an air blockage. A simple filter change is enough to do the trick.
Your Heat Pump is Not Cooling
- The reversing valve is broken
If the air being blown by the vents is hot, the reversing valve could be faulty. The reversing valve controls the air conditioning and heating properties of the refrigerant. A broken valve should be replaced by a skilled technician.
- Low refrigerant charge
When there is a leak or the level of the refrigerant goes too low, the heat pump works harder to cool your house down. Let a technician check whether there is a leak before topping up the refrigerant.
If the Heat Pump Runs Continuously
- It is too cold
If it is too cold outside, the unit is likely to run almost constantly. This isn’t necessarily a cause for alarm.
- A faulty compressor contractor
This is the component that regulates the amount of power that flows into your heat pump. If it breaks down, the heat pump is likely to run near-constantly. Have a professional service the machine.
